How to generate images from a selected category/post in this code?

I want to add a image slider in my wordpress blog. I searched through the internet and found the following code.

    <div id="featured" >
        <ul class="ui-tabs-nav">
            <li class="ui-tabs-nav-item ui-tabs-selected" id="nav-fragment-1"><a href="#fragment-1"><img src="images/image1-small.jpg" alt="" /><span>15+ Excellent High Speed Photographs</span></a></li>
            <li class="ui-tabs-nav-item" id="nav-fragment-2"><a href="#fragment-2"><img src="images/image2-small.jpg" alt="" /><span>20 Beautiful Long Exposure Photographs</span></a></li>
            <li class="ui-tabs-nav-item" id="nav-fragment-3"><a href="#fragment-3"><img src="images/image3-small.jpg" alt="" /><span>35 Amazing Logo Designs</span></a></li>
            <li class="ui-tabs-nav-item" id="nav-fragment-4"><a href="#fragment-4"><img src="images/image4-small.jpg" alt="" /><span>Create a Vintage Photograph in Photoshop</span></a></li>
        </ul>
        <!-- First Content -->
        <div id="fragment-1" class="ui-tabs-panel" style="">
            <img src="images/image1.jpg" alt="" />
            <div class="info" >
            <h2><a href="#" >15+ Excellent High Speed Photographs</a></h2>

            </div>
        </div>
        <!-- Second Content -->
        <div id="fragment-2" class="ui-tabs-panel ui-tabs-hide" style="">
            <img src="images/image2.jpg" alt="" />
            <div class="info" >
            <h2><a href="#" >20 Beautiful Long Exposure Photographs</a></h2>
            <p>Vestibulum leo quam, accumsan nec porttitor a, euismod ac tortor. Sed ipsum lorem, sagittis non egestas id, suscipit....<a href="#" >read more</a></p>
            </div>
        </div>
        <!-- Third Content -->
        <div id="fragment-3" class="ui-tabs-panel ui-tabs-hide" style="">
            <img src="images/image3.jpg" alt="" />
            <div class="info" >
            <h2><a href="#" >35 Amazing Logo Designs</a></h2>
            <p>liquam erat volutpat. Proin id volutpat nisi. Nulla facilisi. Curabitur facilisis sollicitudin ornare....<a href="#" >read more</a></p>
            </div>
        </div>
        <!-- Fourth Content -->
        <div id="fragment-4" class="ui-tabs-panel ui-tabs-hide" style="">
            <img src="images/image4.jpg" alt="" />
            <div class="info" >
            <h2><a href="#" >Create a Vintage Photograph in Photoshop</a></h2>
            <p>Quisque sed orci ut lacus viverra interdum ornare sed est. Donec porta, erat eu pretium luctus, leo augue sodales....<a href="#" >read more</a></p>
            </div>
        </div>
    </div>

Now, instead of putting images manually, I want to use images/texts from a selected category/or post… so how can I do that?
